Title: Synthesizer receiver
Inventor: SASAKI TADAO
IPC: H03J7/02
Filed: 1979-02-07
Abstract: PURPOSE:To secure performance of AFT although the carrier has some shift by forming the same PLL to both the local oscillation signal at the channel selection time and the intermediate frequency signal after reception. CONSTITUTION:Local oscillation circuit 15 is formed with VCO. At the channel selection time, the oscillation signal of circuit 15 is divided through divider circuit 21 and then compared through comparator circuit 23 with the output of reference frequency oscillation circuit 24 which is divided by divider circuit 25. This comparison output is used for the control signal for VCO of circuit 15. Under reception, the output of intermediate frequency amplifier circuit 16 is compared with the output obtained by dividing the output of circuit 24, and this comparison output is used for the control signal of circuit 15 to lock the intermediate frequency to the prescribed value. As a result, AFT can be performed although the carrier frequency has some shift, thus ensuring the proper reception.

Abstract: PURPOSE:To obtain the winding having high reliability in passing wires in wiring by a method wherein, when the tip of a wire passes through a core window, the middle part of the wire which will be wound subsequent to the wire already wound is pulled in the direction where it does not interfere with the wire which passes through the core window, and stress is given to the wire already wound. CONSTITUTION:When the tip part 15' of a wire 15 is moved to the upper part of a core window 2 by rollers 21 and 21', as the middle part 15'' of the wire 15 is moved to a roller couple 30, stress is added to the wire 15'''' located between the already wound wire 15''' and the core winding part 3 and a roller couple 30.
